Abstract

La présente invention concerne un appareil de refroidissement différentiel dun tube de pellicule plastique. Lappareil et la méthode comprennent lutilisation dune filière dextrusion de pellicule soufflée qui extrude un tube de pellicule plastique vers le haut. Un système de refroidissement dair applique de lair réfrigérant à travers au moins une surface du tube de pellicule plastique. Au moins une vanne détranglement est couplée à une pompe de mise sous pression qui procure un fluide actif sous pression, de préférence de leau. Les vannes détranglement sont positionnées pour projeter le fluide actif sous pression à partir des sorties des vannes détranglement vers des arcs circulaires du tube de pellicule plastique, les arcs circulaires du tube de pellicule plastique étant inférieurs à la circonférence du tube de pellicule plastique pour fournir une pellicule plastique tubulaire soufflée avec une variation contrôlée de lépaisseur.
